In more than a decade of operation, NASA's Chandra X-ray Observatory has transformed our view of the high-energy Universe with its ability to make exquisite X-ray images of star clusters, supernova remnants, galactic eruptions, and collisions between clusters of galaxies. As Chandra expands the realm of the known, it continues to raise new questions and point the way for future exploration. This photo blog presents some of Chandra's most spectacular images in a large and shareable format. Follow Chandra on Twitter
